T on whom it may concern:

Be it known that I, JOSEPH H. LEIDEL, a citizen of the United States, residing at Dresbach, in. the county of Winona and State of Minnesota, have invented certain new and useful. Improvements in Corn- Husking Machines, of which the following is a specification.

his invention aims to devise a novel mechanism for husking corn after the same has been harvested and. cured and the ears snapped from the stalks.

The invention contemplates in combination with a pair of husking-rolls a lifter for detaching the ears from one of the huskingrolls at a point in its travel to admit of the other husking-roll turning the ears to bring the part previously up ermost in a lower position or in such re ation as to insure thorough removal of the husks and corn silk from the ears.

The invention further contemplatespe- 1 culiar means for directing the ears to the husking-rolls, whereby the latter promptly and effectively take holdof the husks and strip them from the ears, said means serving to properly position the ears in their delivery to the husking mechanism.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanyingdrawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features "thereof, still the preferred embodiment is shown in the accompanying drawings, in

which i and mountings belng 1n sectlon.

F1g. 3 1s a Figure 1 is a front. view of a corn-husking machine embodying the invention, the housings of the several pairs of rollers being omitted and one pair of rollers, its gearing, Fig. 2 is a vertical longitudinal section ofthe machine on the line 3 3 of Fig. 2. Fig. 4 is a transverse section of the husking mechanisms, their housings, and the supporting framework. Fig. 5 is a fragmentary perspective view showing the feed-board and guiding means.

Corresponding and like parts are referred I to in the following description and indicated in all the views of the drawings by the same reference characters.

The husking mechanism is preferably inclined to cause the ears to feed by gravitative force, thereby obviating the necessity for providing feeding mechanism ofany kind ,for advancing the ears during the process of stripping the husks therefrom. In the present instance the husking mechanism comprises a pair of husking-rolls, which are arranged with longitudinal edge portions practically in contact, said rolls being geared for simultaneous rotation in opposite direc- 1 tions, whereby their opposing sides move in unison so as to draw the husks from the ears and cause said husks to pass between them. The husking-rolls are disposed in parallel relation and are positively geared by means of cog-wheels, which arefast to extensions of their journals or shafts. There may be as many pairs 0f husking-rolls as desired, each with its adjunctive devices being a duplicate of the other. i

The husking-rolls comprising a pair are represented by the numerals l and 2, the same beingjournaled in bearings applied to cross-timbers 3 and4,'which form elements of a framework. A cog 5 is'fast to an exten sion of the journal or shaft or'each huskingroll, the cog-wheels 5 being of like'diameter and having an equal number of teeth to comp-el the husking-rolls to rotate at a like speed and in opposite directions, whereby the upper portion of each bordering upon the trough or space formedbetween them travels inward and downward, with the resultthat the husking-rolls mutually cooperate to strip the husks from the ears and deliver the said husks between them. Each husking-roll is provided with two rows ofteeth 6 and annular grooves 7, the latter alternating with the teeth. The teeth upon one husking-roll are arranged opposite to the annular grooves of the companion husking-roll, so as to enter the same in the rotation of the rolls. The teeth 6 are, provided in two straight lines, which. are located upon diametrically opposite sides of a husking-roll, the teeth being of chisel form and projecting from the rolls a comparatively short distance, soas not to injure the grain or kernels. A housing 8 is arranged over the upper portion of the husking-rolls and prevents the ears flying from or leaving the husking-rolls duringtheoperation of stripping the husks from the ears.

iIO

The housing 8 is preferably of semicircular form in cross-section and consists of a metal covering, the side portions of which fit close to the outer sides of the husking-rolls, so as not to interfere with the free operation thereof or come in contact with the teeth thereof.

T 0 effect a thorough removal of the husks and cornsilk, it has been found desirable to employ one or more lifters 9, which are arranged with reference to a husking-roll to carry the ears free thereof, while the other or companion husking-roll effects a turning of the ears to bring the part remote from the husking-rolls in position to be acted upon, so that any portion of the husk or corn-silk clinging thereto may be removed. The lifter 9 consists of a plate in the preferable construction and is arranged in the length of the husking-rolls and path of travel of the ears, so as to support the latter during a part of their travel over one of the husking-rolls and while the other husking-roll is serving to turn the same. The plate 9 is preferably of sheet material, such as metal, and is transversely corrugated, fluted, or ribbed with reference to the path of travel of the ears or the length of the husking-rolls, with the result that the ears are prevented from passing too rapidly over the lifter and are sufficiently retarded to insure their turning by the other or active husking-roll. The lifter is arranged over the upper inner portion of a husking-roll and wholly to one side of the space formed between the upper proximal portions of the husking-rolls. By employing more than one lifter and spacing the same apart the ears are turned a number of times, thereby insur ing a thorough removal of the husks and corn-silk therefrom, which is desirable in order not to detract from the commercial value of the product.

Any suitable framework may be devised for supporting the husking mechanism and adjunctive parts. As shown,the framework comprises longitudinal base timbers 10, uprights 11, longitudinal timbers 12, and the cross-timbers 3 and 4E. The longitudinal timbers 12 are inclined corresponding to the incLnation of the husking-rolls. The upper portion of the framework receives the hopper and directing means for guiding the ears to the husking mechanism. The directing means comprises a feed-board 13 and upwardly-diverged guides 14, the latter being spaced from the feed-board a distance to admit of the ears passing freely into the hopper and from thence to the husking-rolls. Side pieces 15 prevent the ears from passing over the ends of thefeed-board and compel said ears to occupy a position so as to ultimately enter the hopper or hoppers preliminary to passing upon the husking-rolls. Each pair of husking-rolls is provided with a hopper 16, the ends and sides of which slope or incline inwardly and downwardly to cause the ears to be received in the space formed between the inner and upper portions of a pair of husking-rolls. A spur 17 is located at the lower end of the feed-board in line with the space formed between a pair of husking-rolls and in line with the center or angle formed between the side portions comprising the cooperating diverged guide 14. of the spur 17 is to prevent an ear entering the hopper crosswise and to effect a turning of the ears, so that they will enter the hopper endwise or approximately parallel with the length of the husking-rolls, so as to promptly be taken up by the husking mechanism, and thereby avoid any possible loss of time and prevent choking or obstructing of the machine. The cars are also positioned by the guide 14, the diverged members of which centralize the ears and cause the same to pass quickly to the center of the space formed between the companion husking-rolls.

A counter-shaft 18 is arranged crosswise of the framework and is journaled at or near its ends in bearings secured to the side timbers 12, and said shaft is driven from a suitable source of power in any convenient way and, as shown, is provided with a sprocket-wheel 19, around which is adapted to be passed a The purpose sprocket drive-chain (not shown) in the usual way. A bevel spur-gear 20, fast upon the counter-shaft 18, is in mesh with a companion spur-gear 21, fast upon the extended journal or shaft of a husking-roll. In the event of a series of husking mechanisms being embodied in one machine each pair of husking-rolls is operated in the manner specified.

In the operation of the machine the ears of corn to be husked are fed to the board 13 by hand or in any manner found most advantageous, and said ears pass from the board into the hopper, being properly positioned by the spur 17 and the guide 14 in the manner stated. As the ears are received upon the husking-rolls the teeth 6 penetrate the husks and tear or strip the latter therefrom, said husks being drawn between the rolls and dropped therefrom after being drawn between the rolls. As the ears in their travel come in contact with the lifter or lifters they are temporarily disengaged from one husking-roll and at this time are turned by the other husking-roll so as to bring a new portion in position to be acted upon by the husking mechanism, with the result that any portion of the husk or corn-silk adhering thereto is removed. The housing or covering 8 holds the ears in position and prevents any turning thereof during their travel over the husking-rolls.

Having thus described the invention, what is claimed as new is 1. In corn-husking mechanism, the combination of complemental husking elements, and means arranged in the path of the ears and adapted to temporarily remove the ears during their travel irom the action of one of the bushing elements to admit of the other husking element turning the ears to bring a new portion thereof in position for the action of the husking elements during the remainder oi the travel of said ears thereover.

2. In husking mechanism, the combination of complemental husking elements, and a liiter arranged in the path of the ears to effect temporary disengagement thereoi from one of the husking elements, said lirter being corrugated or roughened to prevent a too rapid movement or the ears thereover.

3. The combination or a pair of huskingrolls, and a liter arranged to extend over the inner upper portion or one of said huskingrolls and in close proximity thereto to effect temporary disengagement of the ears therefrom and to permit turning of said cars by the companion husking-roll, substantially as and for the purpose specified.

4. In combination, husking mechanism, guide means for directing the ears to the husking mechanism, and a spur located in advance of the receiving end of the guide means to prevent the ears entering the husking mechanism crosswise.

5. In combination, corn-husking mechan- 1 6. In combination, a husking mechanism,

a hopper comprising inwardly or downwardly sloped or inclined walls, an inclined feedboard, a spur at the lower edge of said feedboard and in line with the space formed between the husking elements, and a guide between the hopper and husking mechanism comprising upwardly and forwardly diverged members.

7. In combination, husking mechanism embodying cooperating husking-rollers, and a liter arranged in the path of movement of the ears to eifect temporary disengagement thereofi'rom one of the husking-rollers to permit the other roller to effect turnin ofsaid ears, said lirter comprising a curved p ate arranged over and concentric with one of the rollers, as specified.

In testimony whereof I aflix my signature in presence of two witnesses.
